Dexter Season 8 Confirmed as the Final?

CPC:
For a while now, it’s been rumored that the upcoming eighth season of Dexter will be the final in the serial killer drama. Big wig David Nevins would never confirm this, though, stating only that they had an endgame in sight. Now, it looks like the cat is out of the bag.

My theory is he'll get caught AND killed. Death penalty, but after the thing's Deb as done she'll start to slip and his death will be the last straw. When he dies she'll pick up his legacy and the series will end with her as a serial killer.
